High air duct of countercurrent closed cooling tower

Abstract

The invention belongs to the field of high air ducts, and particularly relates to a high air duct of a countercurrent closed cooling tower. The high air duct of the countercurrent closed cooling tower comprises an air duct, wherein an electric motor is arranged in the air duct; the lower end of the electric motor is connected with a bearing; and the lower end of the bearing is connected with fan blades. A base ring is connected to the lower end of the air duct, a connecting cover is arranged on the inner side of the air duct, a clamping groove is formed in the inner side of the connecting cover, a bolt is arranged in the connecting cover in a penetrating mode, a water channel is arranged in the air duct, an air channel is arranged at the upper end of the water channel, a nozzle is connected to one end of the water channel, a water inlet is connected to the other end of the water channel, a pressurization port is connected to one end of the air channel, the outer surface of the electric motor is connected with a connecting block, and a hole penetrates through the inner side of the connecting block. According to the high air duct of the countercurrent closed cooling tower provided by the invention, the problem that a traditional closed cooling tower high air duct and a fan are difficult to disassemble and assemble is solved, and meanwhile, a technical scheme capable of conveniently cleaning the fan blades of the high air duct is provided.

Description

technical field [0001] The invention relates to the field of high air tube devices, in particular to a high air tube of a counterflow closed cooling tower. Background technique [0002] "Closed cooling tower (also called evaporative air cooler, closed cooling tower or closed cooling tower) is to place the tube heat exchanger in the tower, through the circulation of air, spray water outside the tube and circulating water in the tube. Heat exchange ensures the cooling effect. Since the circulating water is a closed loop in the pipe, it can ensure that the water quality is not polluted, which protects the efficient operation of the main equipment and improves the service life. When the outside temperature is low, the spray can be stopped Water system, play a water-saving effect. With the implementation of national energy conservation and emission reduction policies and the increasing scarcity of water resources, closed cooling towers have been widely used in industries such as ...
